Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to the systems, the devices and
methods for preventing a device user from forgetting and losing
important personal items as the user moves between different
locations. More particularly, this invention is related to a
reminder device implemented with a trigger for triggering an audio
output for pronunciation of a designated reminder message upon a
specific reminder-required activity.
2. Description of the Prior Art
The problem of forgetting important person items when a person
moves from one location to another becomes very annoying. It is
desirable to provide a device to remind a person to check important
personal items such as wallet, cellular phone, coat, eye glasses,
airline ticket, passport, etc., before leaving for next destination
such that forgetting and losing important personal items may be
prevented.
Many Patents and Patent Applications have disclosed reminder
devices. However, such devices are generally related to reminding a
person to carry out certain activities such as take medications, at
particular time of the day. The device for providing reminder
messages at designated times is however not practically useful for
reminding a person to check and prevent the loss of important
personal items due to the fact that the activities are usually
taking place at different times of the day. A reminder message that
is provided at fixed time according to a predefined schedule
generally will not satisfy the requirement of timely providing a
requirement message when such reminder messages are necessary and
required because a pending event or activities is soon to take
place.
In Published US Application 20070129888, a spatially associated
personal reminder system is disclosed. The device enables users to
create reminders and associate those reminders with
entering/exiting particular trigger areas. A user's portable
computing device triggers an alert/displays a reminder based upon a
user entering and/or exiting a trigger area. A user interface
supported by the portable computing device allows a user to
terminate the reminder so it will not trigger again, to defer the
reminder so it triggers again after an elapsed time, to reset the
reminder so that it triggers again only if a user leaves the area
and then returns, to request a last chance, causing the portable
computing device to remind the user again upon exiting the area to
ensure the user did not forget to act upon the reminder, or to edit
the reminder. The user interface also enables users to graphically
define trigger areas within the physical world to be associated
with personal digital reminders using geo-spatial imagery.
However, such system and method is still limited in the practically
usefulness due to the facts that the reminder messages are related
to particular locations. A person often travels to very different
kinds of places that have different geo-spatial imagery. The
triggering of a digital reminder depending on locations and the
characteristics that are spatially associated will not effectively
resolve the problems faced by a typical device user.
Therefore a need still exists to provide new and improve system to
resolve the difficulties and limitations discussed above.
SUMMARY OF THE PRESENT INVENTION
It is therefore an aspect of the present invention to provide new
and improved devices, systems, and method to provide reminder
messages by anticipating and detecting activities or events that
would generally require a reminder message. A reminder message
device is provided with detector or sensor to detect such
activities or events to trigger the delivery of such reminder
messages. The delivery of such messages may be in different forms
including textual display of a short message on a wireless
communication device, an audio pronunciation, or a voice mail that
a person may listen privately on a cellular phone a device with an
earphone.
Specifically, it is an aspect of the present invention to provide a
novel device for detecting an event related to entering or driving
a car to travel to a destination. Detector and sensors are provided
to detect activities of opening a car door by using a electronic
car key, turning on the roof light when entering into the car, or
pushing down the gas pedal to accelerate the car to a certain speed
that results an initial acceleration and movement of a device
carried on the car to at certain speed. A reminder message is
delivered when sensing or detecting such events or activities.
Another aspect of the present invention is to detect a user's
activity in preparing to leave a place to travel to next
destination. The activities include placement of a car key in a
pocket or purse and then taking the car key from the pocket or
purse. The activities may include pulling up a handle of a wheeled
luggage or turning on a cellular phone after an airplane is landed
before the passengers are ready to leave the airplane cabinet. The
activities may also include turning off a notebook computer and
place the computer into a luggage. These typical activities provide
indications that a reminder message may be necessary because a
person is preparing to leave. A reminder device in this invention
is provided with sensors or detectors to detect such events or
activities to deliver reminder messages.
Briefly, in a preferred embodiment, the present invention discloses
a reminder message device that is provided for triggering by an
event or an activity to deliver a reminder message. In a preferred
embodiment, the reminder message device is integrated with an
electronic door opener for a car and triggered by a door-opening
signal of the electronic door opener to deliver a reminder message.
In another exemplary embodiment, the reminder message device is
integrated with a roof light inside the car and is triggered by
turning on of the roof light in opening a car door for delivering
the reminder message. In another preferred embodiment, the reminder
message device is implemented in a wireless communication device
such as a cellular phone or a Personal Digital Assistant (PDA)
device and is triggered by a turning of operation of the wireless
communication device for delivering the reminder message. In
another exemplary embodiment, the reminder message device is
implemented in car key that includes a light sensor. The reminder
message is triggered by a sudden change of an intensity of light
detector by the light sensor to deliver the reminder message. In
another exemplary embodiment, the reminder message device is
implemented with a portable electronic device that includes a
global position system (GPS) to detect a motion of a certain speed
to deliver the reminder message. Another preferred embodiment, the
reminder message device is implemented with a portable electronic
device by including an accelerometer to detect an acceleration to
deliver the reminder message. In another exemplary embodiment, the
reminder message device is disposed on a pull-up handle of a
wheeled luggage that includes an accelerometer to detect a pull-up
operation of the pull-up handle to deliver a reminder message.
In summary reminder message device for delivering a reminder
message is disclosed in this invention. The reminder message device
includes a reminder message delivering circuit provided for
triggering by a reminder-message event or activity to deliver a
reminder message. In an exemplary embodiment, the reminder message
delivering circuit is triggered to deliver an audio output of the
reminder message. In another exemplary embodiment, the reminder
message delivering circuit is triggered to deliver a text message
for receiving by a wireless communication device as a short message
(SM). In another embodiment, the reminder message delivering
circuit is triggered to deliver a message to a wireless
communication device as a phone message of as a voice mail message.
In an exemplary embodiment, the message delivering circuit is
triggered by an activity of a user when preparing to leave for
another destination. In another exemplary embodiment, the message
delivering circuit is triggered by an event indicating a device
user is moving at a certain speed or acceleration in moving from
one location to a destination.
These and other objects and advantages of the present invention
will no doubt become obvious to those of ordinary skill in the art
after having read the following detailed description of the

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 shows and exemplary embodiment of an electronic door opener
100 for a vehicle of the present invention. The electronic door
opener 100 includes a door control signal transmitter 105 to
transmit door control signals to either unlock or lock a door of a
vehicle 110. The electronic door opener 100 further includes a
reminder message processor 115 with a pronunciation audio port 118
to pronounce a reminder message when the user of the electronic
door opener operate the electronic door opener 100 either to lock
or unlock the door of the vehicle 110. The electronic door opener
100 further includes a user interface 120 to allow the user of the
door opener 100 to designate specific reminder messages to remind
the user of the door opener not to forget either the personal items
or important events. The reminder message may include message to
remind the user of the electronic door opener about personal items
such as wallet, cellular phone, passport, eyeglasses, or any items
that the user of the electronic door opener may forget when opening
the door of a vehicle to drive to another location. The messages
may be changed or inputted to the reminder message processor 115
depending on the circumstances that would demand such reminder
message.
FIG. 2A shows an alternate embodiment of a reminder message device
150 integrated with a roof light 155 having outer screws for
screwing onto the roof light adapting outlet. The reminder message
device further includes a timer 160 for setting a predefined time
delay to allow a driver to enter and sitting in the car then
pronounce a reminder message to reminding the driver or
passenger(s) of the car not to forget to check the personal items.
Generally, the roof light 155 is turned on when the door car is
opened and the roof light will usually stay on for a short time
period. As the power is on, the reminder device 150 is turned on
also to pronounce designated reminder messages to remind a driver
or a passenger of the vehicle about personal items or important
event.
FIG. 2B is a perspective view for showing an alternate embodiment
of reminder message device 170 that includes a cigarette lighter
plug 175 for plugging into a cigarette lighter in a car. As the
ignition key of the car is turned on, it also turn on the cigarette
lighter thus providing power to the reminder message device 170 to
pronounce the reminder messages for reminding the person sitting in
the car before the car is driven off not to forget important
personal items.
FIG. 3A shows another exemplary embodiment of a reminder message
device 180 implemented together with a cellular phone 185 as a
special feature of the cellular phone 185. The cellular phone is
usually turned on when an airplane is landed and the passengers are
ready to leave the airplane cabinet. As the cellular phone 185 is
turned on, the reminder messages may be presented to the cellular
phone user either as a short message (SM) displayed on the screen
of the cellular phone. Alternately, the reminder message may be
directly pronounced from the phone as an audio output. Or,
alternately, the reminder message device may just send a ring to
the cellular phone for the cellular phone user to push a button to
listen to the reminder messages as a voice mail. The cellular phone
user thus receives the reminder messages as private messages
instead of directly pronouncing the messages in the public place.
The reminder message device may be integrated with other kinds of
portable electronic devices in addition to a cellular phone, such
as a personal digital assistance (PDA), a digital camera, a
global-position system (GPS) device, an iPod, a portable DVD
device, or any other kind of portable electronic devices. The
reminder messages device implemented with these devices may be
turned on soon as these devices is turned on to provide the
reminder messages either as direct audio output, a text message in
the form of a short-message or a voice mail message that a device
user can listen as a private message from these devices.
FIG. 3B shows another exemplary embodiment of a reminder message
device implemented in a portable electronic device such as a
cellular phone, a personal digital assistance (PDA), a digital
camera, a global position system (GPS) device, or any other types
of portable electronic devices. The portable electronic device 200
is implemented with a reminder message processor 210. The reminder
message processor 210 includes a reminder-message requirement
detector 215 to detect a reminder message required activity. The
detection of such activity may include the detection of a signal
transmitted to a car to unlock a car door or to open or close a
garage door. Such activities would often require the pronunciation
of a reminder message because the device of the portable electronic
device 200 is probably driving from one location to another
location. The reminder message processor 210 may include a user
interface to allow a user to input or designate reminder message
required activities and reminder messages. For instance, a cellular
phone often includes a GPS for detecting the location of the user.
When the GPS detects the rate of location change of the user as the
user of the phone is riding in the car is greater than the walking
speed, then a reminder message may be pronounced because the user
of the cellular phone is now moving from one location to another in
a vehicle and a reminder message may be necessary.
Alternately, FIG. 3C shows that portable electronic device 230 may
include an accelerometer 235 to detect an acceleration, e.g., when
a car is driven off initially with an acceleration greater than a
threshold value, and turning on the reminder message device to
provide reminder messages in different forms such as a text
message, a direct voice reminder or a voice mail message.
FIG. 3D shows a portable electronic device such as an electronic
car door opener 240. The electronic car door opener is implemented
with a reminder message device 245 that includes a light sensor
248. As a user of the electronic car door opener 240 ready to leave
a room, the electronic car door opener 240 is either placed into a
pocket or a purse or alternately the car door opener is taken out
from a pocket or a pulse. The light sensor will detect a sudden
light intensity change. The sudden large amount of light intensity
change provide a signal to the reminder message device 245 to turn
on and provide the reminder messages in either a text message, a
direct pronounce voice message, or a voice mail type of
message.
FIG. 4 shows an alternate embodiment of a reminder message device
of this invention implemented with a luggage 250 that has a pull-up
handle 255. A reminder message device 260 is formed as part of the
pull-up handle by placing the reminder message device 260 as part
of the top bar 265 of the pull-up handle. The reminder message
device further includes an accelerometer to detect the pull-up
motion of the pull-up handle 255 when the user of the luggage is
ready to leave. The accelerometer of the reminder message device
260 can be further turned on as the luggage is placed in a car and
the car is driven off. Acceleration of the car together with the
luggage is detected by the accelerometer included in the reminder
message device 260 to turn on the reminder message device to
provide the reminder message as a text message, a direct pronounce
voice message or a voice mail type of message.
FIG. 5 is a flowchart for illustrating the processes of
implementing in a portable electronic device to trigger the
pronunciation a reminder message to a user of the portable
electronic device. The process starts (step 300) with a user of an
electronic device input through a user interface designated
activity and corresponding reminder messages (step 305). Then the
electronic device starts a process of detecting of a reminder
message required activity according to the designated activity
inputted by the device user (step 310). The reminder message
required activity might include activity of opening of a garage
door or turn on the ignition key of a car, etc. Upon the detection
of the reminder message required activity, the reminder message
processor activate the audio output port to pronounce the reminder
messages as inputted and designated by the electronic device user
(step 315), then the process ends (step 320) and return to the step
of detecting whether there is a reminder message required activity
again (step 310).
According to above descriptions, this invention discloses a method
to deliver a reminder message. The method includes a step of
triggering a delivery of the reminder message upon detecting or
sensing a reminder message required event-or-activity to prevent a
person from forgetting or losing a person item. In an exemplary
embodiment, the step of sensing the reminder message required
event-or-activity includes a step of detecting or sensing an
activity when the person preparing to leave a place for a next
destination. In another exemplary embodiment, the step of sensing
the reminder message required event-or-activity includes a step of
detecting or sensing an activity when the person preparing to drive
a motor vehicle. In an exemplary embodiment, the step of sensing
the reminder message required event-or-activity includes a step of
detecting or sensing an activity when the person turning on a
wireless communication device after an airplane is landed. In an
exemplary embodiment, the step of sensing the reminder message
required event-or-activity includes a step of detecting or sensing
an activity when the person preparing to leave an airline cabinet.
In an exemplary embodiment, the step of sensing the reminder
message required event-or-activity includes a step of detecting or
sensing an event when the person is traveling in a motor vehicle
over a certain speed or having an initial acceleration when the
motor vehicle starts to drive to reach a certain traveling speed.
In another exemplary embodiment, the reminder message is delivered
optionally in different kinds of messages as a text short message,
a direct audio pronunciation message, a phone message, or a voice
mail message.
FIG. 6 is a flowchart to show the process steps carried out by a
reminder message device implemented with a door lock. To start the
operation (step 400), the reminder message device implemented in
door lock has a sensor to detect a key inserted into the key hole
to open the door (Step 410). Upon a detection of the key turning to
open the door, the user action triggered signal transmission is
activated (step 420) and a reminder message triggering signal is
transmitted from the reminder message device and received by a
reminder message display or announce device (step 430). The
reminder message display or announce device receives the user
action triggered message to display or announce a pre-recorded
reminder message (step 440). The user then acknowledges that the
reminder message is received and that the actions indicated in the
reminder message is accomplished (step 450) before the processes
are ended (step 460). An acknowledge and action-completed message
may also be transmitted from the reminder message display or
announce device back to the reminder message device implemented
with the door lock. Alternately, the acknowledge and
action-completed message may also be transmitted from the reminder
message display or announce device to a different message device as
preset on the reminder message display or announce device.
FIG. 7 is a flowchart to show the process steps carried out by a
reminder message device implemented with an electronically
activated device. To start the operation (step 500), the reminder
message device implemented in the electronically activated device
has a sensor to detect a user action to activate the electronically
activated device (Step 510). Upon a detection of the user's action,
an optional check is carried out to determine if there is a time
delay after the user's action is set to determine a time for
transmitting a user action triggered signal (step 515). At the end
of the time delay, the user action triggered signal transmission is
activated (step 520) and a reminder message triggering signal is
transmitted from the reminder message device and received by a
reminder message display or announce device (step 530). The
reminder message display or announce device is activated to display
or announce a pre-recorded reminder message (step 540). The user
then acknowledges that the reminder message is received and that
the actions indicated in the reminder message is accomplished (step
550) before the processes are ended (step 560).
An exemplary the electronically activated device may comprise a
garage door opener. As a user ready to leave for work in the
morning or coming back from work in the evening, the user push a
button of a garage door opener to open and close the garage door. A
user action triggered transmission of reminder message may be
activated to remind a person the user of the garage door opener of
the tasks or objects that required to be reminded. The reminder
message may be displayed or announced on a cell phone of the user
with a pre-recorded message or images transmitted to the cell phone
as the user triggered transmitted reminder messages. The garage
door opener is only one example among many of the electronically
activated devices of this invention. Different kinds of
electronically activated devices, such as a television, computer, a
car door opener, a gaming device, etc., may also be implemented
with the reminder message device to provide timely and pre-recorded
reminder messages either by the user or by another third party so
that the reminder message may be effectively delivered at the right
moment to the user.
FIG. 8 is a flowchart to show the process steps carried out by a
reminder message device implemented with a mechanically activated
device. To start the operation (step 600), the reminder message
device implemented in the mechanically activated device has a
sensor to detect a user action to activate the mechanically
activated device (Step 610). Upon a detection of the user's action,
as an option, a check is carried out to determine if there is a
time delay after the user's action is set to determine a time for
transmitting the user action triggered signal (step 615). At the
end of the time delay, the user action triggered signal
transmission is activated (step 620) and a reminder message
triggering signal is transmitted from the reminder message device
and received by a reminder message display or announce device (step
630). The reminder message display or announce device is activated
to display or announce a pre-recorded reminder message (step 640).
The user then acknowledges that the reminder message is received
and that the actions indicated in the reminder message is
accomplished (step 650) before the processes are ended (step

For example, a mechanically activated device may be an oven that is
turned on by a mechanically turn knob to turn on the oven to bake a
cake for thirty minutes. The oven is implemented with a reminder
device to detect the user action to turn on the oven. Then a time
delay of thirty minutes is set for transmitting the user action
triggered signal to either a cell phone of other kinds of reminder
message display of announcement device such as a land-lined
telephone, a television or an alarm device to remind the user to
the time is up for turning off the oven.
Another exemplary mechanically active device may comprise a door
lock. When a door lock is unlocked and remains unlocked to a preset
length of period, i. e., a preset time delay, a reminder message
signal transmission is activated. A reminder message signal is
transmitted to a cell phone or an alarm device to notify a user
that the door is unlocked for a time period according to a pre-set
time delay. A similar reminder message may also be pre-set for an
electronically operated garage door opener to notify a user that a
garage door is opened for a prolong period of time.
Although the present invention has been described in terms of the
presently preferred embodiment, it is to be understood that such
disclosure is not to be interpreted as limiting. Various
alternations and modifications will no doubt become apparent to
those skilled in the art after reading the above disclosure.
Accordingly, it is intended that the appended claims be interpreted
